Configuration of the process-data channel
You can use the Process Data Channel (PZD) to exchange actual and setpoint
values cyclically between the Compax3 and the Profibus master / Profinet
controller.
The PZD is adjusted separately for the following transfer directions:
Profibus-Master / Profinet controller
⇒
Compax3
Compax3
⇒
Profibus-Master / Profinet controller
set separately.
The control word 1 (Profibus Master / Profinet controller
⇒
Compax3) and the
status word (Compax3
⇒
Profibus-Master / Profinet controller) are always on the
PZD.
The further assignment is configurable. The values available for selection depend
on the selected operating mode.
The values assigned to the PZD appear in the selected order in the telegram and
can be read or written at the respective address of the process image. Please take
into consideration, how many words are assigned to the respective object.
Depending on the configuration that is set, the resulting PPO type is displayed in
the "Profibus telegram" wizard window (in the status line of the wizard window).
You can use this value for the configuration of the Profibus master.
With Profinet, you can read out the PKW type and the telegram size for setting in
the Profinet Controller.
After this, the "Starting address" identifies the address at which the PZD will be
placed on the input / output range of the master.
With Profinet, the PPO type is displayed, in the control and C3 configuration
however, a distinction is made between acyclic channel and IO data and they are
set individually.
